Try this:

@property (nonatomic, retain) IBOutlet GMSMapView *googleMapView;
@property (nonatomic, retain) CLLocationManager *locationManager;

- (void)showCurrentLocation {
    _googleMapView.myLocationEnabled = YES;
    [self.locationManager startUpdatingLocation];
}

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
            GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:newLocation.coordinate.latitude 
                                                                    longitude:newLocation.coordinate.longitude 
                                                                         zoom:17.0];
            [_googleMapView animateToCameraPosition:camera];
        //...
}
